Hexagonal stainless steel pipe bushing with threaded ends

Value Brand

Value Brand 316 Stainless Steel Hex Reducing Bushing 1-1/2 in x 3/4 in

SKU CH-JT3B-MA16N

Connects 1-1/2 in male NPT to 3/4 in female NPT with 316 stainless steel rated to 2500 psi steam at 350°F

  • 316 stainless steel resists corrosion in harsh environments
  • Male 1-1/2 in NPT to female 3/4 in NPT connects different pipe sizes
  • Forged construction meets ASME B16.11 for structural integrity
  • Threads cut to ANSI/ASME B1.20.1 ensure reliable sealing
  • Rated for 2500 psi steam at 350°F for demanding service

Fitting for Size Transition

The ZORO SELECT 1RTW2 is a hex reducing bushing made from 316 stainless steel that conforms to ASTM A-182. It connects a 1-1/2 inch male NPT thread to a 3/4 inch female NPT thread. The fitting meets ASME B16.11 specifications for forged fittings and ANSI/ASME B1.20.1 thread standards. No thread sealant is pre-applied on the component.

Upgrade to Corrosion Resistance

This bushing replaces carbon steel or lower-grade stainless fittings in systems handling aggressive fluids. The jump is worth it when service conditions demand the superior corrosion resistance of 316 alloy. Threads conform to ANSI/ASME B1.20.1 ensuring compatibility with existing NPT piping networks. Installation requires the user to supply appropriate thread sealant for the joint.

Pressure and Temperature Headroom

The fitting is rated for a maximum steam pressure of 2500 psi at 350°F within specified operating ranges. It comfortably handles high-pressure steam and process lines built to ASME B16.11 design limits. Headroom diminishes if operating temperatures exceed the rated envelope or if the media attacks 316 stainless steel. Buyers needing larger step-down ratios or different thread standards must select alternative fittings.

Questions about this item

What thread sizes must the mating pipes have for this 1-1/2 in by 3/4 in reducing bushing?

The bushing has a 1-1/2 inch male NPT thread on one end and a 3/4 inch female NPT thread on the other, both cut to ANSI/ASME B1.20.1.

Which sealing method is required during installation since none is pre-applied?

Apply PTFE tape or pipe-thread compound to the male threads before tightening; the fitting ships dry and relies on the installer to seal the joint.

How often should the 316 stainless steel threads be inspected for galling or corrosion in steam service?

Inspect at each scheduled shutdown; the 316 alloy resists attack up to 350 °F and 2500 psi steam, but thermal cycling can still cause thread deformation over time.
